Acer Liquid Z530

Samsung Galaxy S8

The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.

2.Has integrated graphics

Acer Liquid Z530

Samsung Galaxy S8

With integrated graphics you don’t need to buy a separate graphics card.

3.Uses big.LITTLE technology

Acer Liquid Z530

Samsung Galaxy S8

Using big.LITTLE technology, a chip can switch between two sets of processor cores in order to maximise performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximise battery life.

4.Has out-of-order execution

Acer Liquid Z530

Samsung Galaxy S8

Out-of-order execution is used in CPUs to make use of instruction cycles that would normally be wasted due to delays.

2.has built-in optical image stabilization

Acer Liquid Z530

Samsung Galaxy S8

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

4.Has a dual-lens (or multi-lens) main camera

Acer Liquid Z530

Samsung Galaxy S8

A dual-lens camera captures two images and overlays them. This technology creates sharper images, especially in low light conditions, and allows you to use effects such as softening the background.

For example

Huawei Honor Magic 2

5.Has phase detection autofocus for photos

Acer Liquid Z530

Samsung Galaxy S8

A phase detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

6.has a flash

Acer Liquid Z530

Samsung Galaxy S8

A flash is good for low-light environments, and can sometimes be used as flashlight.
